Ordos

The Ordos loop is a region of northern China, west of Beijing. The region is located between the three sides of the Yellow River to the north, east, and west and the Wei River to the south, forming a loop in the provinces of Shanxi, Shaanxi, Gansu, and Ningxia near the border with Mongolia. During the Han dynasty, the Ordos was constantly the location of warfare between the imperial armies of China and the hostile Xiongnu tribe to the north, and the Ordos would later be conquered by Han armies.
